Did I Mess This Up with Him?

I recently just meet my crush's best friends. They are all hot! I brought along my best friend, and I totally shut down. I wasn't talking at all. At the end of the day, my crush and I ending up kissing. I feel as though his friends may have persuaded him a little about not dating me, but then again my crush marches to his own drum. so what is he thinking? did I mess up? I mean he did kiss me in the end.
